late model suspension swap

[63longfleet]

Hi all, been lurking the site for a little bit, fixin to start my 63 long fleet project and have those budget issues we all share. I have read the threads on swapping control arms and such from a later model but is there a way to maintain the 6 lug bolt pattern. Im sure this may be a stupid question and it is prob. been addressed in here before but I havent found it yet. Thanks
